WIRELESS DOOR LOCK CONTROL SYSTEM:
HINT:
 S    Troubleshooting of the wireless door lock control system is based on the premise that the door lock
      control system is operating normally. Accordingly, before troubleshooting the wireless door lock control
      system, first make certain that the door lock control system is operating normally.
 S    If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
      check and replace the Wireless Door Lock Control Receiver as the last step.
